ENLARG EABLE TELESCOP I C CASE OR TRAVELING-BAG.

SPECIFICATION forming part of Letters Patent No. 606,221, dated June 28, 1898. Application filed September 16, 1897- Serial No. 651,896. (No model.)

To all whom it may concern:

Be it known that we, KARL KRUPPA and OSCAR LEHRER, citizens of the United States, residing at Fort Reno, in the county of Canadian and Territory of Oklahoma, have invented certain new and useful Improvements in Enlargeable Telescopic Cases or Traveling Bags; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertai'ns to make and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part of this specification.

Our invention-relates to traveling bags and cases, and especially to that class of bags known in the art as telescopic,- in that they-- are composed of two separable parts,each slidable on the other, whereby the bag or case is closed and its size increased or diminished perpendicularly at will.

It is the object of our invention to provide and produce a case or bag that can be automatically adjusted and its size extended both longitudinally and laterally with equal facility and ease as it could heretofore be extended perpendicularly, and thus to. provide a case enlargeable into three or more sizes, according as the principle might have been extended in its construction, as occasion. should arise for its use by the owner, avoiding the necessity heretofore existing of keeping a number of different-sized valises, travelingbags, or cases to carry larger or smaller quantities of articles compactly forthe purposes of each particular trip, and also providing a case that could be turned by unfolding into a full-dress-suit case with the same facility and case that it could be folded into an ordinary-sized traveling-bag, thus saving a great expense to the general public and supplying a long-felt want. WVe attain these objects and ends by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of our complete device. Fig. 2 is a transverse section of our complete device. Fig. 3 is a longitudinal section showing it with one extension extended. Fig. 4 is a longitudinal section showing it with two extensions extended.

Fig. 5 is a perspective view of the lower part of our receptacle, showing the manner of folding. Fig. 6 is a perspective view of our improved hook and catch. Fig. 7 is a detailed view of our folding triangles.

Referring to said drawings by letter, A denotes the top half or section of our complete case.

B denotes the lower half-section of our complete 'case'.

. C denotes our original improved adjustable handle complete; D, the bottom section of handle, which can be constructed of wood or metal and is made in a solid piece with a slot through same extending along its center sufficiently far to permit adjustment to all extensions of case or bag E, thumb-bolt to pass through .top of case and bottom section of handle D and secure same to case, which when loosened by turning the top permits the adjustment of the handle to any longitudinal extension of the case by sliding the handle and also by revolving around said thumbbolt to permit adjusting to any lateral. extension, and by buckling'the short strap F into the ringG at side of case form a perfectly-secured handle when so laterally extended. H is the top section of said handleand is aleather strap or other flexible material fastened at each end of bottom section D with rivets or bolts on either side of slot Lthrough which leather straps J J pass and are buckled together to bind and hold the two halves or sections of the complete receptacle together and also to support the handle.

K K K K are folds in both sections of case when folded toits smallest size; is akin, same folds when enlarged to second size; L, our improved hook and catch, adapted to hold folds in place and give strength and stiffness to the sides of the. receptacle; M M M M, our original triangles, constructed of the same material that the sides of the case are con structed of and of like weight and thickness, which may be either of leather, wood, or pasteboard or metal, covered solidlywith leather, cloth, or other flexible material, bound around the edges with steel or other metal rods or wires underneath the outside cover to give strength and stiffness to both the sides and triangles; N N N N, rows of stitching between the four triangles through the leather, cloth, or other material with which they are covered, (and with which the sides and bottom of the receptacle are covered, forming a strong durable flexible hinge between the adjoining points of said triangles (shown in Fig. 7) when folding or unfolding the sections of said complete case to enlarge or diminish the same; 0 0, leather protectors stitched on the outside of covering to triangles to prevent the triangle-points from puncturing the covers when folded and to reinforce same; P P, like leather protectors to reinforce corners of triangles where they are joined to the main body of case-sections by stitching, as shown in the drawings. Said protectors are sewed through and through the material as the O O protectors above described; Q, adjoining points of the inside of the triangles and stitchings; r, Fig. '7, our four triangular pieces, which when covered and joined together by stitching, as above described, form the folding and enlarging features of our invention.

- S S S and Sare the spaces between the adjoining sides of our complete set of triangles before they are covered over with leather, cloth, or other material and stitched together, as above described, and each space is sufficiently larger than the other to fold up smoothly when the case is diminished, space S being double the width of space S and so 011; i, metal rods or wires extending around top of case under the cloth or leather covering which forms the outside to strengthen and stiffen the same; 2, similar metal rods to support corners perpendicularly underneath cover, as above set forth.

Our case is constructed, as above set forth, of pasteboard, cardboard, wood, or metal or other stiff material covered with leather, cloth, or other flexible material, reinforced and strengthened with wire or metal rods around the top, bottom, and up the corners when desired, with our original complete handle con structed, as heretofore set out, of wood, metal, and leather, adjustable to all extensions of case automatically. parts may be made as light or as heavy as desired and may haye as many trays or inner receptacles as desired constructed on the same principles asthe lower section of case, only The case and all of itssmaller to fit inside thereof, with our trian-' gular folding arrangement applied to the construction and operation of said trays or inner receptacles, so that they may be automatically enlarged or diminished asthe case is so enlarged or diminished, making a complete enlargeable telescopic case and inner receptaoles more perfect and complete in all its details than any other case yet designed.

Having thus described our invention, what we claim as our invention and as original and novel, and desire to secure byLetters Patcut, is

1. In an eXtensible-traveling-bag section the combination of a bottom, side walls rigidly connected thereto, an extension-botto1n, and extension side walls foldably connected with the extension sides and bottom and constructed and arranged to be turned down inside of the upturned bottom extension to form new end walls, when the case is diminished.

2. In a traveling-bag having duplicate sections telescoping the one into the other, a section comprising in its construction an end wall foldably connected to an extension of the bottom proper and to collapsible side extensions and constructed and arranged to be turned down inside of the upturned bottom extension to form a new end wall when the case is diminished.

3. In an extensible-traveling-bag side-wall section the combination of four triangular pieces, constructed of rigid material, bound all around with an endless metal tire or rod, covered on both sides with flexible material stitched through and through between each triangular piece where they join and form a square, and also where they join' the other parts of the side wall, reinforced at the corners, and points of the triangles, substantially as described.

4. A traveling-bag handle having a slot longitudinal thereof and means secured to the bag for slidably and pivbtally connecting the handle to the bag.

In testimony whereof we affix our signatures in presence of two witnesses.
